    摘要： A plasma CVD process comprises conducting film formation in a reaction chamber capable of being substantially vacuumed in which a plurality of cylindrical substrates are spacedly arranged on a concentric circle in said reaction chamber such that a desired discharge space is formed at the central position of the inside of said reaction chamber and a cathode electrode is disposed at the central position of said discharge space, by introducing a film-forming gas into said discharge space and applying a high frequency power from a high frequency power source to said cathode electrode to produce plasma between said plurality of cylindrical substrates and said cathode electrode, whereby forming a deposited film on the surface of each of said plurality of cylindrical substrates, characterized in that an earth shield comprising a non-magnetic material and a soft magnetic material or an insulating material being stacked is disposed at each of the opposite end portions of said cathode electrode, and a very-high-frequency energy of a frequency range of 60 MHz or more from said high frequency power source is applied to said cathode electrode to produce plasma in said reaction chamber whereby forming a deposited film on the surface of each of said plurality of cylindrical substrates. And a VHF plasma CVD apparatus suitable for practicing the plasma CVD process.
